What is Menstrual Cycle?
Menstruation, also known as a period or monthly, is the normal and regular discharge of blood and mucosal tissue (known as menses) from the inner lining of the uterus through the vagina.
Menstrual Cycle
A female, after attaining puberty, every month one of the ova in the ovaries matures and gets released, once in every 28 days, by the process of ovulation. Due to the rise and fall of hormones, the lining of the uterus becomes thick and spongy before ovulation in order to receive the fertilised egg. When the egg is released from an ovary around day 14 in the cycle, the thickened lining of the uterus provides nutrients to an embryo after implantation. But, if the egg is not fertilised, this lining of the uterus or womb breaks and sheds its lining and passes out of the body through the vagina in the form of blood and tissue, this flow of tissue and blood from the vagina is commonly known as menstrual flow. It lasts from 3-5 days. After this flow stops, the uterus starts preparing itself, again for the fertilised egg. If it does not receive the fertilised egg, the same set of events are repeated.
Periods normally start between ages 11 and 14 and continue until menopause at about age 51. It usually lasts from 3 to 5 days.
Common symptoms and signs of this cycle include acne, bloating, sore breasts, feeling tired, food cravings, mood changes, irritability, lower back pain, headache, and fatigue.
